Beit' known that I, VILLIAM FRITZ, acitizen'of the United States, residing in the city and'county'of Philadelphia, State of Penn- .sylvania, 'have inven'ted a new and useful Lettering andDe'corating Device, of which the following 'a specification.

My-'"present invention relates to blanks previously coated 'with chocolate and still in afiplastidcondi'tion, and consists in novel means for discharging one or more streams of liquid chocolate upon a single blank to form letters ordesigns.

It further consists of a novel construct-ion.

of an open work table and'means for intermittently agita ing, and shaking the same.

It "fu rther consists of a novel construction of channels above said table and means for closin 'l and or enin the same. wherebv ,e a g U malleabl larger blanks m y be kept in straight line for receiving the decoration.

It, further cons1stsof novel means for pushing the blanks in transverse rows across the open work table.

Th from iw'henthe same are,read 1n COHDQCilOn with It further consists of a novel-construction of a, feeding table, whereby the blanks are fed in longltudina'l and transverse rows to said open work table.

extends an upright pipe 21.

These ribbons are guided and supported by a table 6, having longitudinal strips 7, and 'a-refiprovided with. top and bottom transverse ribs 8the lower of which engage the-grooves or the transversely grooved rollers 4.

9 designates a tank mou-nted'jon legs 10,

and having a water inlet 11 'at 'the bottom and an overflow 12 at its 'top. A Container:

13 having a 'semicylindrical bottom and verv tical walls is arranged'in the tank I9 and "receives'a shaft- 14 and paddles 16 to agitate the liquid coating in the container 13, which is kept at the Water in tank 9. A lifting pump chamber '17 below and in communication with the c0nta iner13 contains an eccentric'allv mounted roller '18 in proper temperature by the a diametrical slot 20 of which is a slidable piston blade 19.

From the outlet of the pump chamber 17 A transverse pipe 22 at the upperend of pipe 21 has a narrow slot on its lower side *for spraying liquid chocolate on top of the blanks. A lower transverse pipe 23, in communication upper side and sprays the bottom "of the blanks on the open work'table. The said table has two transverse bars 24,)24sec11red to the vertical sides 25. In slots ofthetra'nsverse bars 24, 24, at the ends of the open work table, are secured pointed longitudinal vertical plates 26; Springs or elastic bands 27 are fastened between the bars'24, 2-l and to the pointed ends of the plates 26. 28" designates a bracket riveted to the-vertical sides 25 having an'opening into which' is loosely fitted an upright pin 29 hearing the transverse roller 30 directly beneath theelasticcbands or springs 27. 'By the-action of the roller 30 and pin 29, in combination with "8 0 with the pipe 21,- has a narrow slot in itsa lever 32 and a ratchet 31 which "engages said lever, the elastic bands or sprm-gs 27 will be caused to vibrate-and sha k'e the'excessof coatin from the blanks OH-the 0 en work table. 1

53- 34 designate longitudinal.twin metal strips the lower edges of which are arranged in close proximity to the' elastic bands or springs-27. The'ends-ofs'aid strips '34, 34 are bent upwardly, Fig. At one end of the open-work table 't he' s aid upwardly bent ends of the strips 34,-"34 are fastened in slots provided insa bridge 35.

At the op'positeend of theopen-work table I the upwardly bent ends of some of the ,strips are fastened in slots provided in a transverse bar 36 and the upwardly bent ends of the alternate strips are fastened in slots provided in a second and adjacent transverse bar 36'.- Said bars 36 are mounted to move endwise in a standard 37, and journaled in an opposite standard 37 are correspondingly threaded screws 37 b which extend into and engage the bars 36 and are provided with intermeshed spur gears 38, Fig. 4. llhe strips-34, 34 are laterally adjustable strips to regulate the spaces between .the strips 50 that diflerent sizes of of, chains 43 which are run over disks44' having outwardly widening notches 45 to receive alternately the transverse bars '41. The disks 44 are fastened on shafts mounted in standards 46. Said standards also sup- -port shafts 48 on which are idlers 47. The projecting-pins 42 on the transverse bars 43 35 are fastened so that they register with the channels made between the'twin. metal strips 34 and when the chains 43 are. driven by gears 49 said ,pins' 42 will push the blanks through the channels and across the open work apron. I

50 designates, a container slotted on its underside. Paddles or plates 52 fastened the Container 50 thus leaving small openings and when the machine .is operated, the liquid coating will run in one or more streams or strings upon a single blank, causing ridges corresponding to the letters or designs of plate 55. The plate 55 is clamped to rib 56 with a set'screw so that it may be readily changed. 57 designates an eccentric strap and pulley. The end of the strap and the rib 56 are loosely secured to a transverse bar creams may be handled. A knob 40 is fas-- on a shaft serve to agitate liquid coating A plate 54 having a slot like that of the con- 58 which slides in the-; slot of bracket 5 when the eccentric isrot ated. 9

61 is a discharging apron mounted on transverse rollers 60, carried by a table 62, provided with supports 63.

64 designates tight and loose pulleys through which the machine is driven (see Figs. 1 and 2). 65 is a driving connection for thereceiving mechanism. 66, 67 and 68, Fig. 3, are gears of a train; the gear- 67 beingarranged to actuate the vibrator and the 1 gear 68 to drive the pushing mechanism, 69 is'a driving eonnectionfior the discharge apron 61, and 70 a driving connection for the shaft 51 ofthe container 50;

The operation of the machine is as follows:-Water is let in at inlet 11in tank 9 and being heated by steam or gas, not shown in the drawings, to the proper temperature the liquid coating is poured in container 13. The blanks placed on the receiving. apron will, when the machine is operated, bring them in transverse rows in the channels on the open work table between the spray pipes 22 and 23 where theyare coated, the excess of coating being thrown off and caused to fall back into the container 13. Before'the blanks leave the open work table, the plate '55 is drawn across the slot of the slottedv container 50 and hence the liquid coating 95,

runs in one or more strings or streams on to the blanks leaving ridges similar to the perforation in plate 55 on each of the blanks. As the blanks leave the open work table they are taken on the discharging apron 61 which runs into a cold room, not shown in the drawings, or they may be cooled ed by some other device.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:
